George Karl Says He's Getting Death Wishes For Calling Carmelo Anthony A Ball Hog

Ex-NBA coach George Karl says more than 100 hoops fans want to see him 6-feet under ... revealing he's been on the receiving end of death wishes for bashing Carmelo Anthony on Twitter.

Karl coached Melo on the Nuggets from 2005-2011 ... and while Denver made the playoffs for most of their time together, the two never really got along.

Of course, 70-year-old Karl hasn't held back when criticizing Melo in the past ... saying he was selfish and a liability on defense, which ruined the Nuggets' chances at an NBA title.

Now that Melo is hoping to help LeBron James and the Lakers win a championship in 2022, Karl has fired off some shots at the 37-year-old ... trolling Anthony's comments about losing sleep over his quest for a ring.

But, Karl wasn't all negative about the guy ... backpedaling a bit and saying, "I've said it before -- one of the great scorers the game has ever seen. He’s a HOFer and his Jersey should hang in Denver."

And then, Karl went right back to critique mode ... even referencing his battles with neck and throat cancer.

"He Wasn’t a team first player or good defender here in Denver," he added. "And it upset us when he asked for a trade especially after I was sick."

Karl faced a ton of backlash from Melo stans for his jabs ... and addressed the angry fans with yet another tweet Tuesday night.

"I think at least 100 people told me on here to die or rot in hell in the past 24 hours," Karl said. "Cmon folks. That’s not kind or cool."

"Lighten up and celebrate life!!"

When a user asked what he said, Karl didn't mince his words.

"That Melo was a ball hog and s****y defender in Denver."

Melo fans are known for being some of the most passionate backers out there ... so who knows if they'll take Karl's advice.
